Authorities say an apparent suicide bombing has killed at least three people outside a police complex in eastern Pakistan.

Lahore police chief Haider Ashraf says several people were wounded in the blast.

Live television footage from the scene showed smoke billowing from the building and people fleeing the scene.

No group immediately claimed responsibility for the attack, though the country faces a Taliban insurgency and other threats from Islamic extremist groups.
